  • Patent number: 8219609
    Abstract: Provided is a method and an apparatus for maintaining state information between a stateless environment and a stateful environment. Specifically, a front-end process operates a stateless environment, such as providing web services via the HyperText Transfer Protocol. Because HTTP is inherently stateless, a back-end process operates a stateful environment by managing multiple modules. Some of the modules can be login modules that request login information for an authentication process. The authentication process can be the Java Authentication and Authorization Service (JAAS). The back-end process accumulates state information and transmits the state information to the front-end process when modules request further information. By managing the authentication process from the back-end process, the stateful environment is established for the stateless environment.
